exception error

[Michael Klinosky <mpk2@xxxxxxxxx>]

On a machine running F7, I just tried upgrading the CPU from a Celeron 
to a P-III. I found a cpu that should work (according to a manufactuerer 
tech).

However, twice I got "CPU exception 4 - cpu sync error". I'm sure that I 
don't have to re-install the OS - correct? Iow, something is wrong with 
the cpu, or the MB doesn't like it for some reason.
